When mankind is extinguished from it's presence on earth,all that will be left that signifies his mark,will be the mess that is left behind.
ALL that has ever been done by mankind is to re-arrange the atoms of matter on this planet in the way that mankind deemed it necessary to survive in the short term.
This 're-arrangement' of atoms from matter, is like the Andre PREVIN TV sketch on the Morecambe & Wise show.
When playing the piano, Eric Morecambe says,"I am playing ALL the 'right' notes, just in the 'wrong' order".
So too with mankind,the time was once, when all matter on earth was atomically speaking, in the 'right' order,no longer so,it is is 're-arranged' in the 'wrong' order by mankind,polluting the planet & all living things thereon.
There is no such thing as a 'free lunch', the price will have to be paid in full,eventually & a high price it will be too.
It is the arrogance of American capitalism, that NOTHING matters but 'risk' & 'reward' for a few Americans.
It's time the world woke up to the game & changed it forever.
